Can a Squirrel Get You Sick? Understanding the Risks
While the risk is generally low, yes, can a squirrel get you sick? Squirrels can carry diseases and parasites, although direct transmission to humans is rare. However, it’s important to understand the potential dangers and how to protect yourself.
Introduction: Sharing Our Space with Squirrels
Squirrels, those bushy-tailed acrobats of the urban and suburban landscape, are often seen as harmless, even endearing. They entertain us with their antics as they navigate trees and raid bird feeders. However, it’s essential to remember that squirrels are wild animals, and like all wild animals, they can carry diseases and parasites that, while uncommon, can pose a risk to human health. Understanding these risks and taking appropriate precautions is crucial for maintaining a safe and healthy coexistence.
Disease and Parasite Transmission from Squirrels
Can a squirrel get you sick? The answer depends on several factors, including the health of the specific squirrel, the type of contact you have with it, and your own immune system. While squirrels rarely transmit diseases directly through biting or scratching, they can carry several pathogens that can indirectly affect humans.
- Rabies: Although possible, rabies is extremely rare in squirrels. The Centers for Disease Control and Prevention (CDC) reports that squirrels are very rarely found to carry the rabies virus.
- Tularemia: This bacterial infection can be transmitted through tick and deer fly bites or through direct contact with infected animals, including squirrels. Symptoms in humans include fever, skin ulcers, and swollen lymph nodes.
- Leptospirosis: This bacterial disease is spread through the urine of infected animals. Humans can become infected through contact with contaminated water or soil.
- Salmonellosis: While more commonly associated with food poisoning, Salmonella bacteria can be present in squirrel feces. Contact with contaminated surfaces can lead to infection.
- Ringworm: This fungal infection can be transmitted through direct contact with an infected squirrel.
- Parasites: Squirrels can host various parasites, including:
- Ticks: Which can transmit Lyme disease, Rocky Mountain spotted fever, and other illnesses.
- Fleas: Which can transmit diseases like murine typhus.
- Mites: Which can cause skin irritation and scabies.
- Roundworms: While less common, these parasites can pose a risk, especially to children.
Minimizing Your Risk
Reducing the risk of disease transmission from squirrels involves practicing basic hygiene and taking preventive measures around your property.
- Avoid Direct Contact: The most important rule is to avoid direct contact with squirrels. Do not attempt to feed, pet, or handle them.
- Maintain a Safe Distance: Observe squirrels from a distance. This reduces the risk of being bitten or scratched.
- Wear Gloves: When cleaning up squirrel droppings or handling items that may have been contaminated by squirrels, wear gloves.
- Wash Your Hands Thoroughly: After any potential contact with squirrels or their droppings, wash your hands thoroughly with soap and water.
- Control Pests: Implement measures to control ticks and fleas on your property and on your pets.
- Seal Entry Points: Prevent squirrels from entering your home by sealing any holes or cracks in your foundation or roof.
- Secure Trash Cans: Use tightly sealed trash cans to prevent squirrels from accessing food sources.
- Trim Tree Branches: Trim tree branches that are close to your house to prevent squirrels from using them to gain access to your roof.
- Discourage Nesting: Remove potential nesting sites, such as piles of wood or debris.
When to Seek Medical Attention
If you are bitten or scratched by a squirrel, or if you experience symptoms of illness after potential exposure to squirrels or their droppings, seek medical attention immediately. Be sure to inform your doctor about the potential exposure to squirrels.
The Importance of a Healthy Ecosystem
It’s also important to remember that squirrels play a crucial role in the ecosystem. They help disperse seeds, contributing to forest regeneration. While it’s necessary to protect yourself from potential diseases, it’s also essential to respect squirrels as part of the natural environment. Maintaining a balanced ecosystem can reduce the risk of disease outbreaks by keeping squirrel populations healthy and reducing their interaction with humans.

Frequently Asked Questions
Can a squirrel get you sick? Here are some frequently asked questions and their answers:
What should I do if I get bitten or scratched by a squirrel?
- If you are bitten or scratched by a squirrel, immediately wash the wound thoroughly with soap and water. Apply an antiseptic and seek medical attention from a doctor. They can assess the risk of infection and determine if further treatment, such as a tetanus shot, is necessary. Although rare, it’s best to err on the side of caution.
Are baby squirrels more dangerous than adult squirrels?
- Baby squirrels are not inherently more dangerous in terms of disease transmission. However, they may be more likely to bite or scratch if they feel threatened or are handled improperly. Always avoid handling any wild animal, regardless of age.
How common is rabies in squirrels?
- Rabies is extremely rare in squirrels. According to the CDC, small rodents like squirrels are rarely found to be infected with the rabies virus. This is because rabies is typically transmitted through the saliva of an infected mammal, and squirrels aren’t common carriers.
Can squirrels transmit diseases through their droppings?
- Yes, squirrels can transmit diseases through their droppings, although the risk is relatively low. The main concern is Salmonella, which can cause gastrointestinal illness. To minimize the risk, wear gloves and a mask when cleaning up squirrel droppings, and wash your hands thoroughly afterward.
How can I keep squirrels away from my bird feeders without harming them?
- There are several ways to keep squirrels away from your bird feeders without harming them. Consider using squirrel-resistant feeders, baffles, or placing feeders in locations that are difficult for squirrels to reach. You can also offer squirrels their own food source, such as corn or nuts, in a separate area of your yard.
Is it safe to let my dog or cat interact with squirrels?
- It is not recommended to allow your dog or cat to interact with squirrels. Pets can be injured by squirrels, and they can also contract diseases or parasites from them. Keep your pets vaccinated and use flea and tick prevention medication.
What are the signs of a sick squirrel?
- Signs of a sick squirrel can include lethargy, disorientation, difficulty moving, hair loss, and unusual behavior, such as aggression or appearing unafraid of humans. If you see a squirrel exhibiting these symptoms, do not approach it and contact your local animal control or wildlife rehabilitation center.
Can squirrels damage my home?
- Yes, squirrels can cause damage to your home by gnawing on electrical wires, wood, and other materials. They may also build nests in attics, chimneys, or other sheltered areas. Sealing entry points and trimming tree branches can help prevent squirrel damage.
Do squirrel repellents work?
- Some squirrel repellents can be effective in deterring squirrels, but their effectiveness may vary. Consider using commercial squirrel repellents or natural repellents, such as peppermint oil or cayenne pepper. Rotate the type of repellent you use to prevent squirrels from becoming accustomed to it.
What should I do if I find a baby squirrel that appears to be abandoned?
- If you find a baby squirrel that appears to be abandoned, do not immediately assume it is orphaned. Observe it from a distance for several hours to see if the mother returns.
